HORIZONTAL SECTIONAL BOILER.

SPECIFICATION forming part of Letters Patent No. 672,279, dated April16, 1901.

Application filed November 14, 1900. Serial No. 36,448. (No model.)

To aZZ whom it may concern.-

Be it known that I, Mosns B. MOORE, a citizen of the United States,residing in Reading, Pennsylvania, have invented certain Improvements inHorizontal Sectional Boilers,

of which the following is a specification.

My invention relates to certain improvements in sectional steam-heatingboilers, having for one object the provision of a boiler of to simpleconstruction and economical in action, a further object being to provideimproved means for varying the capacity of the boiler. These objects Iattain as hereinafter set forth, reference being had to the accompanyingdrawings, in Which Figure 1 is a vertical sectional View on the line 11, Fig. 3, of my improved boiler, showing the construction of theintermediate sections and indicating the method of connecting togetherthe sections of the boiler. Fig. 2 is a vertical sectional View on theline 2 2, Fig. 3, indicating the path of the products of combustion.Fig. 3 is a sectional plan view on the line 3 3, Fig. 1, showing theconstruction of theintermediate sections. Fig. 4. is a perspective Viewof one of the intermediate sections. Fig. 5 is a perspective view of theupper part of the furnace-section, and Figs. 6 and 7 are modificationsof the intermediate 0 sections.

. Referring to the drawings, Q is the base of the structure, and in thisbase is the ash-pit, having a door q and with a flange q supporting thegrate G.

3 5 Mounted on the base is the furnace-section A, having a double wallforming a waterchamber A. This section A is, preferably, a casting, andradiating from a central tubular hub or riser H to the outer portion ofthe casing are tubular arms G G, forming the dome of thecombustiomchamber. The arm G is higher than the other arms, extending toa level with the ring a and the upper end of the riser H.

5 In the upper portion of the section A is a fire-door opening I),having a door 6'. The opening in the present instance is partly in thesection A and partly inthe section above it.

P is the dome of the boiler, having a large steam-space and a hollowring or flange around its lower edge, alining with a ring of anadjoining section.

W is a flue extending through the domesection, as shown, and connectedto the stack in any suitable manner.

Between the dome P and the furnace-section A are mounted as manyintermediate sec tions as desired. I have shown two, D and D, in thepresent instance. These sections are identical in form; but the uppersection is reversed, so as to form an indirect passage for the productsof combustion. The section D has a hollow ring cl and a central riser orhub H in line and communicating with the riser H of the section A.Extending from the riser H to the ring d is a partition I, and in thispartition are flue-openings t, forming tubular arms I 1 The arm I is ofthe full height of the section D, while the partition is less than saidheight, forming with the arm G of the section A and the partition of theadjoining section D horizontal passages for the products of combustion,the arm I acting as a deflector.

It will be noted that the solid portion of the partition I extends overabout one-half of the surface of the section D, and the flue-openingsare all on one side of the arm I As the section D is identical with thesection D, all that is necessary in assembling the boiler is to reversethe section D. Its arm I will be in line with the arm I of the sectionD. The arms I will be directly over the solid portion of the partitionI, and its solid portion will be directly over the flue-openings in thesection D.

The lower portion of the dome-section P has a depression P, in line withthe arm I and with the riser H. The several risers are connected bynipples n, and the arms I and 0 G, as well as the portion P of the dome,have openings M, in line with suitable nip ples m, in them, thus formingcirculating-passages between the several sections of the boiler.

S is the steam-pipe secured to the domesection, and S is the return-pipeconnected to the lower portion of the section A.

Lugs B B are preferably cast on the furnace-section A and thedome-section P, and

the bolts?" pass through these lugs, serving to hold the severalsections of the boiler together.

A water-column X, with a gage-glass X of any of the well-known forms, isattached to the dome-section P, and in operation the water-level isalways kept above the bottom of said dome-section.

It will be noted that by constructing and assembling the intermediatesections as shown in my improved boiler the hot gases and products ofcombustion from the furnace first rise vertically between theradiating-tubes G at the top of the furnace-section A. Above these partof the gases strike the bottom of the partition lot the firstintermediate section D and are deflected, passing half-way around theboiler and after striking the deflectingarms flowing with the rest ofthe gases upagain deflected and forced to pass half-way around theboiler in an opposite direction to that taken in the lower section. Thissuccessive rise and horizontal circular motion of the products ofcombustion, as caused by the partitions I and the tubes or arms I isrepeated a number of times, depending upon the number of intermediatesections, until at last they strike the bottom of the dome-section P.Owing to the tubular portion P the gases are compelled to pass entirelyaround the boiler, and they finally escape through the smoke-passage W.By thus causing the heated gases to pass, as described, around thewater-tubes and against the water-filled partitions of theboiler-sections the maximum economy of fuel is obtained. The number ofintermediate sections used in the boiler can be determined by thesteaming capacity required in each case, and the cost of the patternsfor any one boiler is reduced to a minimum, owing to the fact that theintermediate section may be duplicated and the size of the boiler variedwithout any increase in the number of patterns required.

It will be understood that I do not confine myself to the particularform of tubular arms abovedescribed, as I may construct the,intermediate sections wlth a partition having any form of flue-openingstherethrough-for example, circular holes, as shown in Fig. 6.Furthermore, it is not necessary to always have a rim dextending beyondboth sides of the partition I, as I may, if desired, only have it on oneside of the same, as shown in Fig. 7, and having the position of theflue-openings through the partitions reversed in alternating sections.

I claim as my invention- 1. The combination in a sectional boiler of thecharacter described, of a furnace and a dome section, having mountedbetween them intermediate sections, said intermediate sections formingpartitions, a deflecting-arm on each of said partitions and flueopenings through them close to the said arms, the openings on alternatesections being on opposite sides of the boiler and forming with thedeflecting-arms alternate horizontal and vertical passages for theproducts of combustion, whereby the latter are compelled to pass atleast half-way around the boilerin a horizontal plane at each sectionthereof before rising, substantially as described.

2. The combination in a sectional boiler of the character described, offurnace and dome sections with intermediate sections, each of saidintermediate sections consisting of a hollow ring, a riser and a hollowpartition connecting said riser with the ring, there beingradiating-tubes forming flue-openings through one side of the partition,substantially as described.

3. As a new article of manufacture, aboilersection consisting of a ring,a central riser and a hollow partition between the ring and the riser,flue-openings extending through one portion of the partition and anextended portion on the partition forming a deflector for the productsof combustion, substantially as described. a

l. The combination in a sectional steamboiler, of a hollow-sidedfurnace-section having a riser and radiating-tubes connecting the riserwith the hollow sides, hollow intermediate sections, also having. risersand radiating-tubes and a dome-section on top of the intermediatesections, the risers of each section being vertically over one anotherand connected to each other and to the dome-section, and a second set ofconnections near the edge of each section also connecting said sectionstogether and to the dome-section, substantially as described.

5. In a boiler of the characterdescribed, the combination with afurnace-section and a dome-section, of intermediate sections, each ofsaid intermediate sections consisting of a ring, a riser in the centerof said ring, a hollow partition connecting the riser with thering,flue-openings through the partition forming tubes, a hollowdeflecting-arm on each intermediate section, the ring of said sectionextending vertically above and below the partition and the tubes, thesaid intermediate sections of the boiler being alternately reversedthereby forming alternate horizontal and vertical passages for theproducts of co mand vertical passages whereby said products ofcombustion are made to pass in reverse directions through the sectionsof the boiler before escaping therefrom, substantially as described.

7. In a steam-boiler, the combination of a furnace, intermediate anddome sections, water-tubes in the furnace and intermediate sections,said tubes in the intermediate sections forming transverse partitionsacross the boiler, said intermediate sections being made with twohalf-doorways, half-doorways also in the furnace and dome sections,means for carrying away steam generated, and passages through the boilerfor the products of combustion, substantially as described.
